mine is similar spec chipped, huge fmic,-31,scorpion stainless, k and n and abouty 8psi atm. i have a switch in line with the amal so when the amal is functioning i have 15psi. i run the lower boost atm as my fuelling needs setting up. even with lower boost its quick enough to be fun. you cant map mfi, but you can get decent power. the trade off is you can only set up the idle and on boost fuelling, theres no happy medium. ie your setup for say, 15psi. your fuel consumtion will be poor at best as on boost richens it up accross the range. still, on boost is were meltdowns occur due to not getting enough fuel if not setup. DO NOT be tempted to up the boost and drive without setup. although tempting, it will end in tears. 170hp+ is in easy reach. if your paranoid its lean, unplug the amal connector and it knocks the boost right down. bleed valves are ok but setting up on the actuator is more reliable, removes temptation/some wanker fiddling when your backs turned.
